The Lowdown

Alright folks, Rusty here. Let’s be straight with you. It’s been a flat and pretty uninspiring stretch for Kennebunk Beach, and honestly, the next couple of weeks don’t offer much to get worked up about. We’re looking at a long, lean run here.

We start out this Friday afternoon with a bit of weak, short-period swell, maybe 3ft from the ESE. The energy is weak at 64, and with a light southwest breeze, it’s going to be poor. Not worth the paddle. The water temp is sitting at 65°F, which is a touch warmer than usual for early September. That’s one small bonus.

The weekend isn’t any better. Saturday morning is tiny, a mere 2ft, and while it’s clean with a light offshore breeze, there’s just nothing to ride. The afternoon bumps up to 3ft from the E, but the period is still a short 7 seconds, so it’ll be weak and crumbly. Sunday sees a slight bump to 4ft from the NE on the morning, but the wind swings cross-off and the energy is still weak at 171. The afternoon goes glassy, but the swell drops back to 3ft and it’s still poor. There’s a real lack of push in anything we’re seeing.

We’ve got a serious gap in any kind of useful surf from Monday the 7th through most of the following week. The swell just bottoms out, with waves from 0.3ft to 2ft. The periods are all over the place, from a weak 4 seconds to a longer 10 seconds, but the energy is pitifully low, mostly in the single or low double digits. All of it is marked as poor surf conditions. It’s a blank stretch, and you’d be better off doing anything else but staring at the ocean.

There’s a slight pulse of energy on Sunday the 15th and Monday the 16th. The swell comes up to 3ft from the ESE with an 8-second period, and the energy climbs to 95. The morning of the 15th is glassy, which is a positive, but the waves are still just small and weak. This is marginal at best, and I wouldn't call it a standout by any stretch.

Then we slip right back into the flat spell for the rest of the window. There’s a longer period swell (12 seconds) on the 17th and 18th, but the height is tiny – 0.7ft. That’s a classic case of a long-period groundswell with no size behind it. It might groom the water, but there’s nothing to ride.

Look, the bottom line is that there are no true surf options in this whole 16-day forecast for Kennebunk Beach. There’s just nothing on the table. The energy is consistently weak, the swell heights are too small, and the quality is rated poor across the board. It’s a frustrating stretch for a spot that can be fairly consistent. If you’re desperate, maybe a longboard on one of the glassy mornings when the tide’s right, but I wouldn’t count on much. Forecasts can change, conditions might shift, so keep your eyes peeled. But for now, this is about as quiet as it gets.

Rusty, out.

Information about the Kennebunk Beach Surf forecast

The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
